遗传算法工具箱在半主动-TMD参数优化中的应用
|
摘要
提出一种新型的结构振动控制变频TMD半主动控制系统,采用遗传算法工具箱分析了结构的动力放大系数,证实了其对结构振动控制的可行性和有效性。结果表明,单个变频-TMD作为一种半主动驱动器能有效降低结构反应,与传统TMD相比,具有更大的减振频带宽度,而且效果显著。
A new frequency conversion TMD(tuned mass dampers) semi-active actuator system for structural vibration control was proposed.By means of the genetic algorithm toolbox,the dynamic magnification factor of the structure was analyzed and the feasibility and effectiveness of the TMD system to the structural vibration control was proved.The results show that single frequency conversion-TMD as a semi-active drive can effectively reduce the structure reaction,and it has a wider vibration frequency bandwidth and better control effect compared with the traditional TMD.
